Insights into the possible impact of COVID-19 on the endocrine system.

The novel 2019 coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly transmissible and pathogenic coronavirus. Because of the novelty of the COVID-19 pandemic, few data are available on the impact of the SARS-CoV-2 on the different endocrine glands. Previous studies of severe acute respiratory syndrome (SARS) have shown a harmful effect on endocrine function. Notably, the angiotensin-converting enzyme-2 receptor, which is the entry route of coronaviruses to the host cell, is widely expressed in the endocrine organs including testis, endocrine pancreas, thyroid, and adrenal, and pituitary glands. Clinical and biochemical manifestations have been recorded in COVID-19 patients resulting in changes in endocrine activities, which were also recorded during the SARS outbreak in 2003. This review aims to explore the impact of SARS-CoV-2 infection on the function of endocrine glands, based on the latest research in the field.
